[英]How to run command line from Delphi?
How can I run this command from my Delphi application? 如何从我的Delphi应用程序中运行此命令?
C:\\myapppath\\appfolder>appname.exe /stext save.txt
C:\\ myapppath \\ appfolder> appname.exe / stext save.txt
I tried the following code: 我尝试了以下代码:
ShellExecute(0, nil, 'cmd.exe', 'cd C:\myapppath\appfolder', nil, SW_Hide);
ShellExecute(0, nil, 'cmd.exe', 'appname.exe /stext save.txt', nil, SW_Hide);
But it didn't work. 但这没有用。 Can anyone provide a solution?
谁能提供解决方案?
To run a CMD command, you need to use the /C
flag of cmd.exe
: 要运行CMD命令,您需要使用
cmd.exe
的/C
标志:
ShellExecute(0, nil, 'cmd.exe', '/C cd C:\myapppath\appfolder', nil, SW_HIDE);
ShellExecute(0, nil, 'cmd.exe', '/C appname.exe /stext save.txt', nil, SW_HIDE);
However, this will create two different sessions, so it will not work. 但是,这将创建两个不同的会话,因此它将不起作用。 But you can use ShellExecute to run
appname.exe
directly, like so: 但是您可以使用ShellExecute直接运行
appname.exe
,如下所示:
ShellExecute(0, nil, 'appname.exe', '/stext save.txt', nil, SW_HIDE);
But you need to specify the filenames properly. 但是您需要正确指定文件名。
I would do 我会做
var
path: string;
begin
path := ExtractFilePath(Application.ExeName);
ShellExecute(0, nil, PChar(Application.ExeName), PChar('/stext "' + path + 'save.txt"'), nil, SW_HIDE);
end;
in case appname.exe
is the current application. 如果
appname.exe
是当前应用程序。 Otherwise, replace Application.ExeName
with the full path of appname.exe
. 否则,将
Application.ExeName
替换为appname.exe
的完整路径。
